UNDEawArnn Tonen 4 Andrew Barna, Chicago, Ill. Y Application october 3o, isaaseriuno. 301,893 `:i claims. (ci. isahzmi This invention relates to a novel and improved under water torch, which permits the torch to relight automatically under water.

The main object of the invention is to remove K the chance of having vthe torch extinguished under the water and force thefdiver to come to thesurface for re-igniting same.

Another object of the invention is to permit the use of more than same time. Y, g

A further object ofthe invention is to permit the device to be used either as-a straight torch or to be changed by the attachment of` a gooseneck to a torch with any desired angle.

A still further object of the invention is to permit-a reduction in the numbers of lines leading from the surface, to provide more free movement to 4the diver.

A further object of Vthe invention is to permit l the u-se of a branchless Vtorch nozzle-shield.

A stili further object of the inventionis to prevent the mixing chamber from overheating in ,case of back ilash.A

one type of gasV at the A stinfurther object or the invention is to use the device on the surface'or below the surface.

`With the foregoi'ng`and other objects in view.

which will appear Aasthe description proceeds, the invention consists in certain novel features of construction and arrangements of parts hereinafter more fully described, illustrated in the accompanying drawings, andparticularly pointed out in the appended claims, it being understood that various changes in the form, proportion,

quantity, size and minor details of the structure may be made without departingfrom the spirit d or sacricing any of the advantages of the invention.

HThe said under water torch is comprised essentially of al main` body I, a straight head 2, a goose-neck 3, a torch tip l, and a torch tip The inlet valve 6, at its outer yend is attached to the acetylene or hydrogenA line, and at its inner end joins the valve 1, which controls the said gases.

receptacle A28, of the straight head 2.

Between valves 6, and I, is the by-pass 8,

leading to valve 9, which, regulates the ilow of gases to the pilot light, andleads to the receptacle 23, of thestraight head 2.l

The inletvalve I0, at its outer end is attached to the oxygen line and at its inner end connects-to the body portion'lhhousing the high 4pressure valve I2, which controls the ow ofl the oxygen to the prefor` acetylene. vAt its inner end it connects to the by-pass I6, which enters theou'tlet I1.

'The 'outlet'I'L is connectedv to the inner end of the valve 9, and leadsfto the receptacle 23, g

of the straight head 2.

The valve lI, connects with thepassage 26,-and the tube 21, (Fig. 5) which is l secured in the body portion II, and enters the process to escape.

The inlet valve I8, is connected at its outer end either with the oxygen or compressed air pass I3, which enters the outlet 20.

The outlet 20, is secured to the inner end of the valve 2I, and leads to the receptacle 24.

'I'he by-pass 22, enters the body portion II, between the valves I0, and I2, and is leading to the outer .end of the valve 2l, which at its inner end is connected to the receptacle 24, of the straight head 2;

The tube 29, is within the tube 21, and is secured in the body portion II. The by-pass 3B, leads from the inner end of the valve I0, to the control valve 'I4, and leads to the tube-29, with the mixer 3l, suitably placed at its interior adjacent to its outlet, insuring a whirling motion to the gaseous mixture in the mixing chamber 3B, which communicates with the receptacle 28, of the straight head 2.

The straight head 2, consists of a cylindrical body. At its nearend 32, itis provided with the receptacles 23, 24, 25, and 23, to secure thev outletsy 1, 20, and the tubes 33, 21, respectively.

`The suitable interior portion 35, of the straight head 2, is provided with a series of passages.v

The passages 36, leading from the bottom of the receptacle 23,-to the level 31, are conducting the mixed oxygen and gas. The passage 38, leading from the bottom of the receptacle .25, to the level 39, is conducting the oxygen for cutting purposes.I The passages 40, leading from the bottom of the receptacle 2d, to the level 4I, are conducting the oxygen or compressed air.- 'Ihe passages 42, leading from the bottom` of the receptacle 23, to the level 43, are conducting the acetylene and hydrogen for the pilot light. The use of hydrogen, or other suitable gases, prevents corrosion and accumulation of carbon at the opening of the pilot light, which would set in when acetylene is used.

The suitable interior portion 44, of the rotat- 1 line. At its inner end, it ls .connected. to byable goose-neck 3, is provided with theA continuaf The adapter 46, secures the torch tip t, to the goose-neck 3.

'The suitable torch tip d, is provided with four levels, corresponding to the levels of 33, 2li, el, and 43,' of th-straight head 2, and with the continuation of the passages 3S, 33, 4b, and 42,.

'Ihe torch tip 4, is provided with an externally threaded cylindrical portion 41., which retains the adjustable shield 5, at its set position.

'Ihe suitable interior 48, of the shield 5, is provided with a cylindrical portion 49, and an offset 50, at its lower end, by means oi' which it can rest adjustably on the externally threaded portion 4|, of the torch tip 4.

The washers 5I, are securely held cylindrical portion 49, of the shield 5.

The suitable interior cylindrical portion 52, of the shield 5, has an offset 53. The conical portion 54, between the offsets 59, and 53, is provided down by the with ilne threads 53, to induce a whirling motion to the oxygen or compressed air, before passing through the said cylindrical portion 52, and reaching the work. The knurled indentations 55, permit the gases generated during the cutting -flash.

The perforated 11S-nale 55, preyents the mixing chamber 34, from overheatinggin case of back The loop 51, holds-securely together the various outlets and tubes.

The operation of the torch When using only one type of gas for two line method illustration, acetylene gas and oxygen,

the operation is as follows: Provide an oxygen and acetylene tank.` Con- Then the valve I4. 'I'he gas is conducted by the by-pass 80, vinto the inner tube 29, the mixing chamber 34, the receptacle 28, and the passages 36, to the top of the torch tip.

The valve 1. and I4, are to beused to give the proper mixture for the pre-heating ar'ne.

To make use of the pilot light with the said acetylene gas, the valve 3, is to be used for the adjustment of the pilot light. The by-pass 8, for the pilot light starts between the valve E, 1, and conducts the gas tothe valve 9, the receptacle .23, and the passage 42, just below to the top of the torch tip 4, where it impinges against the offset 53,y of the tip shield 5, then by mixing with oxygen passes through the interior cylindrical iop portion 52, of the shield 5.

The by-pass 22, which starts between the valves I0. and I2, conducts the gas to the valve 2l, the

receptacle 24, the passages 40, where it impinges against the offset 50, of the lower interior cylindrical portion of the shield 5, then passes between and around the fine threaded portion 54, and around the top of the torch tip 4, where it impinges against the. oii'set 53, before passing through the rupper interior cylindrical portion 52, of the shield 5. i

"Three line method When using it with acetylene in combination with hydrogen as a pilot light, the above described method has to be repeated, with the exception of closing the valve 9.

- Provide a hydrogen tank. -Connect the regulators to the said tank. Connect. the hose to'the valve I5, which conducts the gas into the by-pass I6, the outlet Il, the receptacle 23, the passage 42, the offset 53, of the shield 5, passing through the interior cylindrical portion 52. This this case forms the automatic lighter.

Four line method By adding a vfourth line, the three line method is to be repeated, with the exception of closing the valve 2|.

Provide an oxygen or compressed air tank.

` Connect the regulators to the said tank. .Con-

tween and around the iine threaded portion 54,k

of the torch tip 4, impinging on the oiset 53, be-

gas in fore passing through the interior cylindrical portion 52, of the shield 5.

When using hydrogen' only, repeat the two line method," substituting hydrogen for the acetylene.
